Specification of letters Patent. Pfmb g t dt J 22 19mg A imation filed October 17, 1am. Serial Rio-867,176,

ToqtZ it may concern:

' Belt.

to provide a hollow metal pin and improved means for balancing the pin so that it'will maintain an upright position.

The invention has for an additional object to provide a bowling pin of the above type embodying means whereby thesame is revented from shifting or j umping'from ts set position'upon the spot. a

is a further object of my invention to produce a bowling pin having the above noted advantageous characteristics which may be produced at small manufacturing cost, and'is very durable and serviceable in actual use. Y

With the above and other objects in iew, my invention consists in the novel features of" construction, combination, and arrangement of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawing, in which,

4 Figure 1 is a side elevation of a bowling pin embodying the present invention; and Fig. 2 is a vertical section of the same.

Referring in detail to the drawing, 1 have illustrated a pin of the character commonly employed in a game of du'ckpins. It is, however, to be borne in mind that the structural features hereinafter referred to, are

applicable as well as to the larger pins whichare use in play n t e se o mari e- The pin 5 includes a hollow bod yfi gt.

general elliptical form, one end of which is truncated to provide a flat base indicated at 7. The body of the pin at its other or ,upper end, merges into a reduced neck portion 8, .said neck portion terminating in the slightly enlarged rounded head 9 of the pin.. This pin is formed of ametallic mixture, in which aluminum predominates. The pin is produced by the process of casting, the molten metal being poured into a suit able mold. The body 6 of the smaller or duckpin is provided in its medial at al times he with an annular peripheral groove or channel lndlcated 'at 10 in which a band of rubber or other resilient.material 11 is placed. The Oll ltelf face of this strip or band extends slightly beyond the peripery of the pin body. It 1s, however, apparent that this provision for the reception of a rubber band, may be l m nated in the construction of the duckpin as well "as the. tenpin.

Inth'e base 7 of the pin, a central hole or open1 ng 12 1s formed, and the head 9 of the pin is provlded with an integral anchoring lug 18 which extends centrally and longitudinally inwardly fromthe wall of the head. This anchoring lug may be either rectangular or cylindrical in form. and is gradually'reduced in width or tapers from lts'end to its point of juncturewith the wall of the head 9. After the hollow metal pm has been removed from the mold, a predetermined quantity of molten lead is poured in the same through the opening 12 and around the anchormg lug 13, as indicated at 14;. After this lead solidifies, it will be reained in place, within the head of the pin y the anchoring lug'as will be readily understood.

By constructing the pin in the manner above ei rp'l'ainedyit will be manifest that all of the pins wil be of precisely the same weight. It is 'quite diflicult, if not impossible, to attain this purpose in he manufacture of the ordinary wooden owling pin. Such pins, after a short period of use, will be found to greatly vary in weight. It is highly desirable, in order that the pins shall offer; uniform resistance to impact, that they at t s We h lrnproved pm is entirely ponstructed of metal which is of requisite thlckness to withstand he impact of the eali g b Wear 'q-fi the pins 1s comparatively insignificant.

It is alsoseen that by the provision of the opening 12 in the base of the pin, molten lead may be poured into the head of the pin to compensate for such wear as does occur In this manner, all of the pins may be main: tained at a uniform weight. It will further be apparent that by providing the pin with the fiat base having the opening 12 therein, there is a comparatively restricted surface which has frictional contact with the floor or alley'so that the movement of the pin will not beretarded when struck by the ball, but

said pin will fall immediately over to a horizontal position, owing to the weight in theheadthereof. I

From the foregoing descriptioln the construction and several advantage'spf my improved bowling pin will be apparent. While I have produced a pin which is manifestly of greaterserviceability than the ordinary wooden pin, it will be appreciatedthat the manufacturing cost thereof is not increased to an appreciable extent. Theneck, head produced.

While I have referred to the preferred manner of retaining the balancing weight within the head of the pin, it will be understood that the present invention also contemplates the provision of other equivalent means for this purpose. I do not, therefore, desire to be limited to the precise structural features above described, but reserve the privilege of resorting to all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent, is Y 1. A hollow metal bowlin pin, a balancing weight insertible into t e head of the pin, and means projecting into the pin head longitudinally thereof to retain 'said weight in position.

2. A hollow metal bowling pin, an anchoring lug projecting into the head of the pin from the wall thereof, and a weight element immovably held in the head of the pin by said lug.

3. A hollow metal bowling. pin, an inwardly projecting tapering lug formed upon the head of said pin, and a weight element surrounding said lug and immovav bly held thereby in the head of the pin.

4;. A hollow metalbowling-pin having an integral tapering lug projecting longitudinally from the wall of the pin and through the head'thereof, and a weight element surroundlng said lug and immovably held by the lug within the head of the pin.

5. A hollow metal bowling pin having an anchoring lug integrally formed with the wall thereof and projecting into the head of the pin, said pin being provided with an opening in its base through which balanclongitudinally into the head of the pin, said plnbeing provided with an opening in its base through which molten lead is adapted to be poured into the head of the pin around said anchoring lug.

7. A bowling pin having a hollow nonflexible body provided with an unobstructed opening in its base, and weighting means insertible through said opening into the head of the pin, the pin head being provided with means to receive said weighting means and retain the same in position with its center of gravity in line with the longitudinal axis of the pin.

8. A hollow bowling pin provided with means whereby fluid metal maybe poured into the head thereof to solidify and constitute a balancing weight, and means on the head of the pin to. retain said weight in position with its center of gravity in line with the longitudinal axis of the pin.

9. A hollow metal bowling pin-provided with an openingin'its wall through which fluid metal may be poured into the headof the pin to solidify and constitute a balancing weight, and means on the head of the pin to permanently retain the weight in position with its center ofgravity in line .with

the longitudinal axis of the pin.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
